TypeSafe AI Launches Jev, a Decision Model That Bypasses LLMs for Speed and Cost

TypeSafe AI, a startup founded by Diogo Almeida—a co-creator of ChatGPT and co-inventor of reinforcement learning from human feedback at OpenAI—has released Jev, a System-1 foundation model engineered for automated decision-making rather than text generation, positioning it as a radically cheaper and faster alternative to large language models for specific computational tasks. The model entered limited early access on September 15, accompanied by a $40 million seed round led by DCVC that valued the San Francisco-based company at $200 million, though post-launch metrics suggest investors are already discussing a significantly higher valuation.
